MD5加密算法，可以加密包含二进制数据的数据块，生成16字节MD5加密数据。(MD5 encryption algorithm to encrypt data blocks that contain binary data, generates a 16-byte MD5 encrypted data.)

des经典加密算法，实现数据交互过程中的保密(des classical encryption algorithm, data confidentiality during the interaction)

转下的源代码程序,此程序需要密码,但可以正常使用,并可对后台进行部分修改(Transfer the source code under the program, this program requires a password, but can be used normally, it may also be part of the background changes)

VC编写的简单DES加密程序，密钥由用户手动输入，可加密字符串(VC prepared by the simple DES encryption program, the key to manually input by the user)

使用MD5算法对数据和文件进行加密，信息安全(Using the MD5 algorithm to encrypt the data and documents, information security)

基于VB的M5数学密码算法源码,有需要的就下载吧。(VB-based M5 mathematical algorithm source code, there is a need to download it.)

以C++语言在微机上实现了美国数据加密标准DES。可随微机软盘任意路径下的任何文件，加密，加密文件可在软、硬盘任何目录下或在网络中传送；另一方面可对软、硬盘中的任何文件进行解密，解密后的文件除在末尾多出几个空格符外与原文件完全相同，绝不影响EXE文件，COM文件或数据库文件的使用。密钥有加密者在键盘输入8个字符。(In c++ language microcomputer to U.S. data encryption standard DES. With the computer floppy disk arbitrary path of any of the files, encryption, encrypt files can be in soft, hard disk any directory or in the network transmission On the other hand, soft, hard disk to the any classify documents, the decrypted file in the end in a few more the space appears with the original documents are all the same, never affect EXE file, COM file or database files use. Key there are JiaMiZhe in keyboard input 8 characters. )

分析RSA算法的应用现状，论证文件加密应用RSA算法的可行性和意义。设计一套完整实用的RSA文件加密解决方案，具体编码实现。对RSA算法进行研究，从常规RSA算法出发，用C++实现RSA加密算法类库，并在32位windows平台封装成组件。在.Net平台引用此组件，实现可以对任意文件进行RSA加密 (Analysis of Application of RSA algorithm, file encryption application demonstration of the feasibility of RSA algorithm and significance. Design of a complete file encryption RSA practical solutions to achieve specific coding. Research on the RSA algorithm, starting from the conventional RSA algorithm using C++ class library to achieve RSA encryption algorithm, and in 32-bit windows platform components into a package. In. Net platform, referred to this component, the realization of arbitrary files on RSA encryption)

使用dll，将vc下进行文件加解密的blowfish方法做成dll文件，从而在vc中调用，隐藏加解密的参变量。(Using dll, under the vc the blowfish file encryption method made dll file, so call in vc, the hidden variable encryption and decryption of the parameters.)

说明：  密码学BM算法的C++实现。可计算100阶m序列的生成多项式(Cryptography BM algorithm in C++. Computable 100 m sequence generator polynomial order)
